[PATCH v3 0/6] iio: accel: adxl372: add peak mode

[Alexandru Tachici]

This series adds the possibility to configure
the device, from sysfs, to work in peak mode. This enables
adxl372 to capture only over threshold accelerations.

1. Create sysfs files for falling_period/rising_period
and thresh_falling_value/thresh_rising_value in events/ dir.
Set INT1 reg for activity/inactivity and push
event code in events fifo on irq.

2. Add additional ABIs in order to explain the
user that setting values in the events/ sysfs files
also changes devices behaviour.

3. Update sysfs docs: renames, added two new
entries for the activity_detect_event/
inactivity_detect_event

  iio: accel: adxl372: Update sysfs docs

1. Device FIFO can now be set in peak mode and only over the
threshold accelerations will be stored.

  iio: accel: adxl372: Add support for FIFO peak mode

Changelog v2 -> v3:
- now use iio_device_claim_direct_mode before setting peak mode
- if peak mode is enabled and not all axis are enabled, filter out disabled axis
data before iio_push_to_buffers
- add events enable attributes: (thresh_rising_en/thresh_falling_en)
- renamed attr: buffer_peak_mode_enable to hwfifo_peak_mode_enable
- squashed event interface related commits into one
